即使索引中没有太多数据也超出了磁盘高水位标记 [英] High disk watermark exceeded even when there is not much data in my index

问题描述

我在本地计算机上使用elasticsearch。数据目录的大小只有37MB，但是当我查看日志时，可以看到：

I'm using elasticsearch on my local machine. The data directory is only 37MB in size but when I check logs, I can see:

[2015-05-17 21:31： 12,905] [WARN] [cluster.routing.allocation.decider] [Chrome]磁盘上的高水位浮雕[h9P4UqnCR5SrXxwZKpQ2LQ]超过了[10％] [Chrome]免费：5.7gb [6.1％]，分片将重新放置在远离此节点的位置

[2015-05-17 21:31:12,905][WARN ][cluster.routing.allocation.decider] [Chrome] high disk watermark [10%] exceeded on [h9P4UqnCR5SrXxwZKpQ2LQ][Chrome] free: 5.7gb[6.1%], shards will be relocated away from this node

对于可能出了什么问题很困惑。有帮助吗？

Quite confused about what might be going wrong. Any help?

推荐答案

来自索引分片分配：

... watermark.high控制项高水印。默认为90％，这意味着如果节点磁盘使用率超过90％，ES将尝试将碎片重新定位到另一个节点。

... watermark.high controls the high watermark. It defaults to 90%, meaning ES will attempt to relocate shards to another node if the node disk usage rises above 90%.

实际索引的大小无关紧要；

The size of your actual index doesn't matter; it's the free space left on the device which matters.

如果默认设置不适合您，则必须对其进行更改。

If the defaults are not appropriate for you, you've to change them.
